HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 737,357, dated August25, 1903.

Application filed April 14, 1903.

To all whom it may concern.-

Be it known that we, HARRY CRUMP and LEON METZ, citizens of the UnitedStates of America, residing at Frank P. 0., in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Hose-Couplers, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-couplers, and more particularly to that class ofcouplers which areadapted to be connected without the use of threads or nuts.

The object of this invention is to provide a hose-coupler which may beconnected by simply forcing the two parts together, the locking of whichautomatically takes place thereby, and while a perfect and secure jointis thus made to provide a coupler in which the parts may be quickly andeasily disconnected.

With the above and other objects in view the invention consists in thenovel construction, combination, and arrangement of parts to behereinafter more fully described, and specifically pointed out in theclaims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout the severalviews, in which- Figure 1 is an outside elevation of our improvedcouplerin its connected position. Fig. 2 is a longitudinal section ofthe same. Fig. 3 is a cross-sectional view'taken on line 3 3 of Fig. 2.Fig. 4 is a cross-section taken on line4 4 of Fig. 2. Fig. 5 is a detailperspective view of one of the locking members.

In carrying out this invention we provide the male portion 1 and thefemale portion 2, each of which is provided on its outer end withsuitable projections, to which the hose is adapted to be connected. Thefemale member 2 is of slightly-greater diameter than the male member andat the outer end is provided with the annular ledge 3, the aperturethrough which is of slightly-greater diameter than the outside diameterof the male member 1. The member 2 has provided at its inner or bottomend a ledge 4, against which Serial No. 162.498. (No model.)

rests the flexible washer 5, which may be which secures them to saidmember 1, and

the said members are formed on a slight curve, whereby their looking orengaging ends will spring behind the annular ledge 3 when the twomembers are connected. I The member 2 has provided just rear of theannular ledge 3 the countersunk opening 7, in which the seg-.

mental disengaging members 8 8 are adapted to rest, the said membersbeing provided intermediate of their length with a pin 9, which passesthrough the outer wall of the member 2, said pin carrying on its outerend the button 10, which projects slightly above the boss 11, which isformed on the member 2, a spring 12 normally holding these members 8within the recess; but when the buttons 10 are forced within boss 11,thereby compressing spring 12, the members 8 will be forced out of therecess, thereby engaging locking member 6 and causing the same to becompressed toward an axial center, whereby they may be moved through theopening provided in the annular groove 3, thus permitting the malemember to be withdrawn from the female member 2. v The bottom end ofthis male member 1, when in its connected position, is forced againstthe flexible washer 5, thereby securing a water-tight joint within saidcoupling.

It will be noted that a substantially smooth passage is afforded for thewater in passing through this coupling.

It will be further noted that variouschanges may be made in the detailsof construction without departing from the general spirit of ourinvention.

Having fully described our invention, what we claim as new, and desireto secure byLetters Patent, is-

1. In a hose-coupling the combination of the male member carrying springlooking members of a female member provided with a flange on said springlocking members be ing adapted to engage the inner surface of saidflange, said female member being pr0- vided with segmental platesadapted to engage and compress said spring looking member whereby thesame may be designated from the rear inner edge of said flange, and aledge formed on the bottom of said female member adapted to seatawasher, said washer being engaged by the inner edge of said malemember, substantially as described.

2. In a hose-coupler the combination with the male member, a pluralityof locking members carried thereby, a female member,

an annular ledge formed on the outer end of said female member, saidlocking member being adapted to engage behind said ledge, a plurality ofsegmental plates carried by said female member, said plates beingnormally held in outward position by means of a spring,

said plates being adapted to compress said r locking members to permitof the withdrawal of the male member, and a flexible washer interposedbetween the end of the male member and the female member to provide awater-tight joint, substantially as described.

In testimony whereof we affix our signa- 3o
